Spain. Honeywell announced that the new HFO-1234yf refrigerant, with low global warming potential, reduced direct emissions to 99.77%, following tests of the air conditioning systems of a fleet of buses.
The multinational claims that the use of HFO-1234yf refrigerant in a normal bus fleet of a medium-sized city would help eliminate the direct emission of 14,000 tons of carbon dioxide per year, which is equivalent to taking about 8,000 cars off the road a year.
The tests were co-financed by the Center for Industrial Technological Development, under the Ministry of Science and Innovation of Spain. Honeywell says HFO-1234yf has a shelf life in the atmosphere of just 11 days, compared to 13 years for HFC-134a and more than 500 years for carbon dioxide (CO2).
"These tests have shown that HFO-1234yf is an environmental alternative to HFC134a technically viable in bus air conditioning systems. The HFO-1234yf is being adopted seamlessly for use in car air conditioning systems. Now, these tests show that their energy efficiency, proven safety, compliance with environmental policies and affordable price can also help reduce the environmental impact of buses," said Paul Sanders, managing director of Honeywell Fluorine Products in Europe, the Middle East, Africa and India.
